Geography World - Water Bodies

According to reports oceans are becoming more acidic. Which of the following is not true about ocean acidification?

Increasing levels of carbon dioxide in the atmosphere is major cause of ocean acidification.

Large amount of evaporation is also a major cause of acidification.

It reduces the availability of carbonate, a substance used by marine species to form shells and skeletons.

Species with high metabolic rates would be more severely impacted by ocean acidi?cation because oxygen binding in their blood is more pH sensitive.

Explanation:

2nd option is incorrect. Large amount of evaporation is not a major cause of acidification.
Ocean acidification is the ongoing decrease in the pH of the Earth's oceans, caused by the uptake of carbon dioxide (CO2) from the atmosphere. Seawater is slightly basic (meaning pH > 7), and the process in question is a shift towards pH-neutral conditions rather than a transition to acidic conditions (pH < 7).
